Quality of Life of Food-Allergic Patients Before, During, and After Oral Immunotherapy.



Oral immunotherapy (OIT) for food allergy is demanding but data on patients’ quality of life (QOL) throughout the process are limited.


To characterize changes in QOL of food-allergic patients during and after OIT.


In a prospective cohort study, the Food Allergy Quality of Life Questionnaire-Parental Form (FAQLQ-PF) was administered to parents of 191 consecutive children aged 4 to 12 years undergoing OIT for food allergy. Questionnaires were administered at OIT initiation, mid up-dosing, upon reaching maintenance, and after 6 months of follow-up. Age- and sex-matched food-allergic children (n = 48) not undergoing OIT served as controls.


FAQLQ-PF scores had significantly improved (decreased) from OIT initiation to reaching full maintenance (emotional impact [EI], 3.66-3.32, P = .001; food anxiety [FA], 3.90-3.32, P < .001; social and dietary limitation [SDL], 3.50-2.94, P < .001; and total score, 3.69-3.19, P < .001) and partial maintenance, whereas no change was noted in control patients. Worse baseline QOL, single food allergy, and a younger age predicted greater QOL improvement. Of the 85 (88.5%) patients who completed the FAQLQ-PF at mid up-dosing and for whom QOL deteriorated, a significant improvement was noted upon reaching maintenance. Additional significant improvement in QOL was observed in the 95 (88.8%) patients who completed the FAQLQ-PF 6 months after reaching maintenance (EI, 3.414-2.993, P = 0.049; FA, 3.37-2.593, P = .001; SDL, 2.989-2.264, P = .001; and total score, 3.266-2.614, P = .001).


The QOL of food-allergic children improves significantly upon reaching OIT maintenance, with additional improvement 6 months later. The detrimental effect of OIT on some patients’ QOL during up-dosing is reversed upon reaching maintenance.
